Application filed June 23, 1926. Serial No. 117,928.

The object of the present invention is to provide a curbstone which shall in general appearance and dimensions be the same as .the usual street curb now employed and which shall be replaceable with the latter.

The particular object of the invention is to provide a curb so constructed that it will dispose of refuse flushed against it, that side of the curb adjacent the street and projecting above it being formed with an opening or spaced openings to receive the dirt and water. The curbstonewill be manufactured in suitable lengths, and will be placed end to end in the usual manner so as to lead the refuse to catch-basins usually situated at the corner or centre of the block.

The invention will'be understood by reference to the accompanying drawing, in which Figure 1 is a perspective view of a short section of curbstone constructed in accordance with the invention, and

Figure 2 is a transverse section through one of the curbstones and a sidewalk and street section, showing the manner in which the curbstone is positioned relatively to the street and sidewalk.

By reference to the accompanying drawing it will be seen that the curbstone A may be constructed of reinforced concrete or other suitable material. The face of the curb which lies adjacent the sidewalk may be vertical, in accordance with the usual practice, or it may extend at an angle, as desired. The face of the curb adjacent the street likewise may be vertical, when in position. Said face may be formed with a plu-- rality of openings a, the bottoms of which are so placed as to lie at the street level, so

that refuse flushed toward the curb may readily pass through the opening and into the inner longitudinal passageway 6. Passageway b is gradually restricted toward its upper end so that the overhanging substantially horizontal upper wall shall be strongly supported. In other words, the left hand inner wall of assageway b is so formed as to have the e ect of a strut extendin to- Willi? the upper right hand portion 0 the cur v v The lower wall 0' may be graded, for'example one-eighth inch to the foot len h, so that water will run off, carrying re se with it, on streets that have not a-natural grade.

I am aware that various attempts have been made by others to provide draining curbstones, but such attempts have not been successful when they were designed to receive refuse from the flushing of streets, be-

cause they were either inherently weak in.

construction and were not capable of replacement for the standard curbstones without.

curbstone formed of concrete or the li e and having substantially parallel side walls merging at their tops into a substantially horizontal top wall structure, the curbstone having a longitudinal internal passageway communicating with a plurality of openings in one side wall adapted to lie approximately at the street line.

2. A draining curbstone formed of concrete or the like, substantially rectangular in cross section and having its top wall sub stantially horizontal and forming a connecting top closure for the side walls, said curbstone having an internal longitudinal passageway, said passageway in cross section having one wall substantially parallel with a side wall, and a converging opposite wall, one wall being formed with an opening placed to lie approximately at the street line, as and for the purpose set forth.

In testimony whereof I have slgne'd my name to this specification. Y
